The sentence that uses the word Amazon correctly is C. "Elena was not very tall, but she defended the basket like an Amazon."
The Amazons were known as fierce, all-female warriors, so the sentence using the word "Amazon" correctly would be one that relates to strength, fighting ability, or combat skills, which is reflected in sentence C. The other options (A, B, and D) do not use the term "Amazon" in a way that accurately reflects the characteristics of the mythical Amazons.
